Thanks, sounds like this might be the problem. I'll check it out.

In the meantime, I went to dslstart.verizon.net and deleted the problem
sub-account. Then tried to create a new sub-account. When I hit "NEXT", the
screen goes blank and "DONE" is displayed at the bottom. If I go back, the
new name is not in the list. Plenty of hard drive space, etc., so I don't
know what the problem is this time.

I'll call Verizon India again some time tonight when I feel like being
talked down to , and post whatever I find out.
